She says plans for the seven acres include a 100,000-sf medical office, 50,000-sf of regular office space, a 218,000-sf multifamily rental complex, 10,000 sf of research and development space along with 100,000 of restaurant, retail and entertainment uses.

"Also, there would be a 640-space parking deck," Johnson tells GlobeSt.com.

A public hearing for the planned unit development and site plan approval has been continued on to the next planning commission meeting, most likely Feb. 4. The city council would consider the plan sometime after that.

The property is made up of 11 parcels, Johnson says. The developers are negotiating for the properties, and have agreements that expire around June, she adds.Johnson says the complex would be built over a strip-mall area where a former self-service dry cleaner spilled chemicals into the soil. There has been talk that it would cost about $8 million to clean up the chemical tetrachloroethylene, she notes."The spill happened sometime in the 1970s, and has settled into the groundwater, with the plume heading toward the nearby creek," Johnson says. "Hopefully they can clean up the groundwater and the soil."

Developers are working on a brownfield redevelopment grant with the Washtenaw County Brownfield Redevelopment Authority to acquire state funds to help with the site cleanup.

"The city would very much like to see the site redeveloped," Johnson says.

However, some residents worry the project would attract too much traffic and would hurt the quality of life with too much density, Johnson cautions.
